French Bistro-Style Lentil Soup with Bacon – 40 min Recipe

Today’s recipe is my French bistro-style lentil soup with bacon, made with smoky bacon in whose rendered fat I sauté onion and garlic, along with celery, carrots, and parsley. And to give it that distinctive French touch, I add butter to the vegetable sofrito. It’s a soup as comforting as it is nourishing, and best of all: it’s ready in 40 minutes!

Eating like in Paris

I once heard my dear Mayte Navarro, a journalist and social chronicler from Caracas, say that when she felt like eating as if she were in Paris, but going to a French restaurant wasn’t in the cards, her husband Alberto would make bistro-style onion soup, they’d uncork a bottle of wine, light the candles et voila: la vie en rose!

The same thing happens to me with this lentil soup, which is the closest thing to what they’d serve in a brasserie in France (although my kids say it would be better if I made an entrecôte accompagnée des frites).

The thing is, I love lentils however they come: with Spanish chorizo and potatoeswith cilantroin a good majadrain saladsand of course I can’t resist a good lentil soup with bacon the way the French eat it.

Bon appétit!

About du Puy lentils

In France, the best lentils are du Puy, a variety that grows in the volcanic soils of Auvergne in the center of the country. They’re so special that the French government even granted them the Appellation D’Origine Contrôlée. I make my lentil soup with regular everyday lentils and they work perfectly.
